The current research examined whether mindfulness promotes offender apologies. In Study 1, we found a positive relation between trait mindfulness and one's disposition to apologize. In Study 2, we found a positive effect of a mindfulness intervention on state apology for a laboratory-induced transgression. In Study 3, an online mindfulness intervention was found to have a positive effect on apologetic (vs. nonapologetic) behavior for transgressors. In Study 4, we found preliminary support for reduced negative self-focused cognitions and emotions when testing a parallel mediation model. We also found support for negative self-focused, as well as positive other-focused, cognitions and emotions when testing a serial mediational model. Our findings are discussed within broader theoretical questions concerning the psychological factors that promote and prevent apologies and the role of mindfulness in constructive responses to transgressions from the perspective of offenders.
